    Abstract: To provide comprehensive (i.e. rapid and sensitive) MS-MS analysis, the inventor employs a time-nested separation, using two time-of-flight (TOF) mass spectrometers. Parent ions are separated in a slow and long TOF1, operating at low ion energy (1 to l00eV), and fragment ions are mass analyzed in a fast and short TOF2, operating at much higher keV energy. Low energy fragmentation cell between TOF1 and TOF2 is tailored to accelerate fragmentation and dampening steps, mostly by shortening the cell and employing higher gas pressure. Since separation in TOF1 takes milliseconds and mass analysis in TOF2- microseconds, the invention provides comprehensive MS-MS analysis of multiple precursor ions per single ion pulse. Slow separation in TOF1 becomes possible with an introduction of novel TOF1 analyzers. The TOF-TOF could be implemented using a static TOF1, here described on the examples of spiratron, planar and cylindrical multi-pass separators with griddles spatial focusing ion mirrors. Higher performance is expected with the use of novel hybrid TOF 1 analyzers, combining radio frequency (RF) and quadratic DC fields. RF field retains low-energy ions within TOF 1 analyzer, while quadratic DC field improves resolution by compensate for large relative energy spread.

    Abstract: The present invention relates generally to a multi-reflecting time-of-flight mass spectrometer (MR TOF MS). To improve mass resolving power of a planar MR TOF MS, a spatially isochronous and curved interface may be used for ion transfer in and out of the MR TOF analyzer. One embodiment comprises a planar grid-free MR TOF MS with periodic lenses in the field-free space, a linear ion trap for converting ion flow into pulses and a C-shaped isochronous interface made of electrostatic sectors. The interface allows transferring ions around the edges and fringing fields of the ion mirrors without introducing significant time spread. The interface may also provide energy filtering of ion packets. The non-correlated turn-around time of ion trap converter may be reduced by using a delayed ion extraction from the ion trap and excessive ion energy is filtered in the curved interface.

    Abstract: A time of flight mass analyser 1 having a drift region 2, an ion packet generator 6, first and second ion reflectors 18,19 and at least one ion detector 20 is disclosed. The drift region 2 has an axis 3, an entrance 4 and an exit 5 and provides for a place wherein ions may be temporally separated according to their mass-to-charge ratios. The ion packet generator 6 injects packets of ions into the drift region 2 at the region's entrance 4 from a beam of ions by intermittently applying an electrostatic field such that the packets of ions enter the drift region 2 in an initial direction which is inclined to the direction of said beam of ions. The first ion reflector 18 is disposed at the exit 5 of the drift region 2 to reflect back towards the entrance 4 ions which are travelling towards the reflector 18 in the drift region 2. The second ion reflector 19 is disposed in juxtaposition to the first ion reflector 18 to reflect packets of ions back towards the first ion reflector 18 through at least a portion of the drift region 2 so that the packet of ions may be reflected to and fro between said first 18 and second 19 ion reflectors and undergo a number n of reflections at the second ion reflector 19. A detector 20 is disposed to detect at least some packets of ions reflected by the first ion reflector 18 which do not enter the second ion reflector 19. The number of reflections at the second ion reflector 19 may be selected by adjustment of an inclination of the initial direction to the axis 3.
